I have AT25640A EEPROM, but I can"t find it in the list of supported devices of True USB Willem Programmer (GQ-2X).
Tried to read AT25640A, using 25C640 from device list with no success.
But AT25128A is in that device list.
Is there a way to read and write to AT25640A, using True USB Willem Programmer (GQ-2X) and how?
Thank you.

| Can you read the AT25640A by selecting AT25128A? If you can partially read/write AT25640A in this way, then you can easily add it. |

Thank you ZLM for answer.
YES, I can read the AT25640A by selecting AT25128A.
Can you, please, tell me how to add AT25640A to the list of supported devices?
I read the manual about the devices.txt file, tried to add the line for AT25640A, similar to AT25128A, but when I start the program I am getting error and Log file is: #ERROR# Line syntax error: "Name="AT25640A SPI EEPROM",ID="XXXX",Class="AT25640",Category="SERIAL_EPROM",MFG="Atmel";"
**** End of log ****
Thank you. |

try those two:
Name="AT25640A (Test2)",ID="XXXX",Class="AT25128",Category="SERIAL_EPROM",MFG="Atmel",CodeSize="8192";
Name="AT25640A (Test1)",ID="XXXX",Class="25C020",Category="SERIAL_EPROM",MFG="Atmel",CodeSize="8192";

Name="AT25640A - worked for me nice. |

Do you mean the Test1 works?
This?
Name="AT25640A (Test1)",ID="XXXX",Class="25C020",Category="SERIAL_EPROM",MFG="Atmel",CodeSize="8192";

No, when I am using: Name="AT25640A (Test1)",ID="XXXX",Class="25C020",Category="SERIAL_EPROM",MFG="Atmel",CodeSize="8192";- programmer does not read correctly, I'm getting something like 3 first lines are repeating to the end with some offset.

It behaving same as when I am selecting 25c640 SPI from the device list.
But when I selected: Name="AT25640A (Test2)",ID="XXXX",Class="AT25128",Category="SERIAL_EPROM",MFG="Atmel",CodeSize="8192";- programmer read EEPROM correctly.
I did not try to write yet. |
